The Battle Ground Before the End of Days

The first six minutes of this is basically an introduction, if you're in a hurry.

Rabbi Daniel Glatstein

It's us against the nations of the world, us against Eisav.  Now Eisav was a wicked guy but there was one merit that Eisav had that was so powerful that we're still dealing with it until this very day. That mitzvah is kibud av v'eim - honouring your father and mother.
